Electromagnetic radiofrequency (RF) sources are widely used to heat up cutaneous and subcutaneous tissues. The subcutaneous morphology of tissue consists of a fine, collagenous and fibrous septa network enveloping clusters of adipocyte cells; however, it is commonly regarded as a ... Mehr lesen
Anomalous acoustic streaming is observed from sharp edges of vibrating solid bodies in fluids. The streaming velocities can be orders of magnitude higher than expected from the Rayleigh streaming at similar amplitudes of vibrations. Acoustic velocity of a fluid relative to a solid body ...

Microwave drying of fruits and vegetables in a domestic oven has been found to result in large textural changes in the product such as puffing, crack formation and even burning due to the inhomogeneous heating of the microwaves. Microwave drying of potatoes is a complex interplay of ... Mehr lesen
Soil mixers are widely used to mix biochemical agents and additives to remediate contaminated soils or drill cuttings and sludges. Through COMSOL Multiphysics simulations, this paper aims to evaluate the effect of geometric configuration of the blades and rotational speed on the mixing ... Mehr lesen
An optimization routine is presented to optimize a hybrid winding geometry for a toroid inductor in terms of the DC-resistance. The hybrid winding geometry consist of bended foil pieces connected through traces in a PCB. MATLAB® is used to create a GUI that visually plots the winding ... Mehr lesen
Most conventional wastewater treatment processes are quite energy-intensive. Global wastewater production is increasing due to growth in population, industrialization, and urbanization, creating an urgent need for energy-efficient wastewater treatment technologies. Moreover, waste ... Mehr lesen
Achieving passive device working over two GHz bands for next generation mobile phone has been strongly desired. This paper investigated the spurious mode suppression for the BAW resonator. The border-frame technique which has been proposed in many literatures is examined here ... Mehr lesen
Flow-induced uvula deformation considerably altered the flow dynamics inside the nose. For a weak soft palate, complete flow occlusion can occur (sleep apnea). Vibration of the airway structures is crucial to better understand snoring generation mechanisms and breathing-related ... Mehr lesen
A continuum, porous medium formulation with non-equilibrium sublimation was developed and validated for freeze drying without and with uniform microwave volumetric heating. The model incorporates the effect of Knudsen flow at low pressure and low permeability freeze drying. The ... Mehr lesen
This paper presents a 2D model of an intermediate temperature ammonia-fed SOFC (400 – 700 °C) based on the Temkin-Pyzhev model of ammonia decomposition. Phenomenological equations are implemented in COMSOL Multiphysics®. The Dusty Gas Model is used to model species transport in porous ... Mehr lesen
